. KALAMEIN MACHINE.

l Application mea Aprilia, 1927. `serial No. 184,112.

Yinvention relates to machines for'the metal covering of door and window stock and other building material products'wherein the material to enter into the construction is required to be covered or partially covered with a metallic covering of sheet material. The same consists primarily of a 'bed Vpla-te element having a multiple of adjustable, vertical guide rollers adjustably positioned relative to the guide plates, having external means ior the adjusting of the same and having a horizontallyv disposed vertically adjustable driving shaft having mounted 'thereupon the collars 'for kalameining the edges of the sheet material-being formed about the wood members.

The primary object of my invention consists in providing a portable machine that may be utilized tor the kalameining oi? building material that may be self-contained, light in weight, and easily moved trom place to place7 thus permitting of vthe doing of the work in the building or in the plant ywhere located. 'Y

A further object of my invention consists vin a machine oi few parts, easily adjusted and one 'that'may be manually operated.

MStill further objects consist in providing a machine upon which the adaptations and `adjustments ot the device may be easily and quickly and `econonfiically made. c

llith A'these and incidental objects in view, the invention consists incertain novel features of construction and` combination of parts, the essentialelements of which are set i'orth rin the appended claims, and a preferred form ot embodiment of which is hereinafter shown'with reference to the drawings which accompany and form a part of this specification. l

'in the drawings Fig. 1 is a top plan view vof the assembled device.

Fig. Q is a sectional side elevation, taken on line 2`2o Fig. il, looking in the direction indicated.`

Fig. 3V is an end view, partially insection, t-aken on line 3 8 of Fig. 1', looking in the direction indicated. l

Fig. 4 is a'sectio'nal elevation in plan, taken on line 4 4 of Fig. 3, looking 'fin the direction indicated.

Fig. 5 is a fragmentary, sectional view, taken on line 5-5 of Fig. 4, looking in the direction indicated, the same being a detail of the adjustable compensating vertical guideway roller support.

Fig. 6 is an end, sectional View, of a Wooden element shown in process of being covered with sheet material, the kalamein rollers being lshown in dotted outline. n

Fig. 7 is a sectional, lside elevation, of a preferred form of embodiment of means' for maintaining the kalameining collars or rollers in position upon the shaft. l

Like referencer characters refer to like parts throughout the yseveral views. i

AIpreferably form `my device of Aa tableelement 1, supported upon structural legs 2, that are secured tothe underside ofthe base. lLongitudinallhorizontal shafts 3 and 4- are connected to the side webs 5 and 6 of the base and are suitablyjournaled therein. Roller supporting frame elements 7 and f8 are slidably positioned upon the shafts 3 andy 4 and are adapted to `being positioned through the actionoi' the threaded shafts 9 and 10 whichv are placed relative to the roller supports 7 and -8 and are moved laterally through theactions of hand wheels 11 and 12, secured to the .outer ends of the shafts 9 `and 10. Cross slots or grooves 13 aredisposed laterally through the bed l of the device-through which the supporting elements for rollers 14 pass. The rollers 14 should be made to* revolve freely upon the vertical shafts 14A `and threaded means are y provided at the upperends of the shafts`14^ to permit of the removal-ot the vertical rollers 14: without fthe dissembling 'of `the machine, as it may be found/desirable to,

grooves 17 and 18. `vThe rollers 14'are then positioned to contact with the metal covering-o1e sheet ymaterial and to press the lsame iirmly againstthematerial to be kalameined. To allowfor differences in Width and to compensate for the same and to facilitate the ease of operation and driving of the device, the base o-f the elements 7 and 8 through which the adjusting shafts 9 and 10 are made topass, as illustrated in detail in Fig. 5, are each provided with cushioning spring 19 disposed within blocks 20, one being disposed upon either side of the base element 2l so that a relatively yieldable adjustment may be made of the vertical rollers relative to the material andyet the cushion provided by the springs 19 allow for the movement of the roller and frame inwardly, or outwardly as the conditions to be met require. A cross shaft 22 is supported within ladjustablebloelrs 23 disposed within a housing 24 and are journaled relative thereto and an adjusting shaft 25 is secured within the 'housing and is positioned through the action of positioning hand wheels 26 and 27 which are in threaded relationship with the shafts 25. Mounted upon this shaft 22 are a series of lralamein collars 28 having a sharpened edge 29, as illustrated in detail in Fig. 7 the object of it is to engage the parallel, longitudinal, edges of the sheet material and to depress the same within the longitudinal grooves 17 and 18 sufficiently, to prevent the spreading of the sheet material after the Same has been removed from the device. The smaller sizes of the machine may be driven by hand by the application of a hand crank of suitable length to the end 30 of the shaft 22, but in the larger sizesrof machines, apulley 31 may be secured to the oppositely disposed endof the shaft to which suitable power application maybe applied and to feed the material through the machine a feed roller 32 is disposed upon the shaft 22 and is made to forcibly engage within the upper surface of the material being passed through the machine. The kalameining collars 28 are journaled about the collet 33 which is .adjustably positioned upon the shaft 22. An outwardly vprojecting rim 3a is dispo-sedupon one end ofthe collet 33. The collet is split as illustrated at 35 in Fig. 7 for a part of its length and two collars 36 and 37 are positioned upon the outer pee riphery of the collet 33, each of which has a locking set screw 38 for maintaining the same in position and in alignment. The objectV of the collar 36 is to maintain the kalamein collar 28 in position upon the collet 33. The object of the collar 37, having a set screw 38 associated therewith, is to lock the collar 37 relative to the shaft and to prevent its rotation upon the collet 33. A setscrew 39 is disposed upon the collar 37, to lock the collet relative to the shaft.

I have illustrated in the drawings, a piece of material of parallel sides being passed through the device, but Ido not wish to be limitedto the kalameining of material of this form, as my device is adapted to the kalameining of materials of various shapes and forms. Y

While the form of mechanism yherein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form ofembodiment herein shown and described, as itk is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.
